Abstract: TITLE:     REVOLVING DOOR                   INVENTOR:  DENNIS LOWE                 ABSTRACT OF THE DISCLOSURE           A revolving door has a plurality of leaves mounted for rotation about a common axis.  To permit collapse of the door in an emergency, the leaves are mounted, at each end, by means of mechanisms that permit such collapse.  There is provided a mechanism for mounting one end of a door leaf, the mechanism having a support plate for rotation about the central axis.  First and second pivot means are mounted on the support plate, and corresponding first and second pivot devices are mounted   on the door leaf.  The pivot means and devices, e.g. corresponding projections and recesses, are such that, the door leaf can pivot about one pair of pivot device and means, whilst the other pair of pivot device and means separate from one another.  Once rotation has commenced about one pair of pivot device and means, they are such that they cannot then be separated, thus securing the door.  Biasing means acts on the door leaf to normally maintain the first and second pivot devices in engagement, and thus to maintain the leaf in a normal extended position.  A latch mechanism is also provided, for use in the biasing means, which automatically locks a latch member when the door leaf is in its normal position.  The latch mechanism can be used with a variety of pivot arrangements.

Abstract: ABSTRACT    Solute Focusing Technique For On-Column Injection in Capillary Gas Chromatography A solute focusing method is applied to the on-column injection of a liquid sample in gas chromato-graphy so that relatively large sample sizes can be used without causing intolerable column flooding. The injection zone of the column is kept originally at a temperature below the solvent boiling point but the temperature in the adjacent downstream zone is kept higher than the solvent boiling point so that the solvent will evaporate and flow downstream, leaving the solute molecules concentrated within a relatively limited length along the column.

Abstract: Abstract The procedure for prolonging the  life of wood-cutting tools relates to the cutting of green wood and comparable organic materials. The applicant has already earlier, more  than 30 years ago, shown that the dulling of tools in such cutting is mainly corrosion of the cutting edge of the tool, which could be almost completely prevented under laboratory conditions by applying a high-voltage direct current. The present invention enables  the dulling  to  be  limited  also  in  practice.  The invention is based on the realization of the specific resis-tance of wood which is sufficient to render unnecessary the electric insulation of the tool or of the wood that is being cut from the frame of the cutting machine, an operation which is difficult  to carry out but was  formerly believed to be indispensable. As taught by the invention, the negative termi-nal of a direct current source is connected with the grounded frame  of  the  machine.  The  current  is  conducted  from  the positive  terminal  of  the  direct  current  source,  using  a suitable anode brush, into green wood acting like an electro-lyte at a point close to the tool  that has to be protected. The wood-cutting  tool  and on  its  side  also  the means  for feeding and supporting the wood will then act as cathodes in the system and they will be protected against wear caused by corrosion.

Abstract: ABSTRACT: "Fast method and device for determining an NMR distribution in a region of a body".            The invention relates to the determination of an NMR distribution in which an alternating gradient field is applied while sampling the NMR signal (FID signal, nuclear spin echo signal). The frequency of the alternating gradient field is com-paratively low (order of magnitude  of 100 Hz) and this field has from a few to some tens of cycles in each measurement period. While an FID signal is being sampled the image frequency field matrix is scanned using a zig-zag (oscillating) line pattern during each line of which data is provided for elements in from a few to some tens of rows in the image frequency matrix. By applying preparation gradient fields, the image frequency matrix can be filled by means of successive zig-zag line patterns which have been shifted with respect to one another and which thus enable a uniform sampling density to be provided in the image frequency space. The filling of the image frequency matrix with signal samples is thus speeded up by a factor of a few to some tens of times by the invention, the energy required for controlling the gradient field coils being substantially reduced at the same time.

Abstract: Abstract Of The Disclosure A downhole tool apparatus has a housing with a compression chamber defined therein.  A fill passage is disposed through the housing for placing the compression chamber in open flow fluid communication with a well annulus so that well fluid may flow into the compression chamber as the apparatus is lowered into a well.  An isolation valve selectively closes the fill passage to trap well fluid in the compression chamber.  An operating element is operated by an actuating piston slidably disposed in the housing.  A first side of the actuating piston is in fluid pressure com-munication with the compression chamber so that a volume of the compression chamber is decreased when the actuating piston moves between a first and second position thereof relative to the housing.  An injection passage is provided for injecting pressurized gas into the compression chamber at a location within the compression chamber such that the injected gas will directly contact at a gas-well fluid interface an upper surface of well fluid that flows into the compression chamber.  The compression chamber is primarily defined by an elongated diametrically irregular annular space, and the gas-well fluid interface moves upward past a number of irregular diameters of this diametrically irregu-lar elongated space, as the apparatus is lowered into a well.
